Tales of a sex in Erebus

 The race of giants know as the Jotnar has recently achieved preeminence in the realm, creating a large empire with many vassels and occupied territories.  For years the Jotnar were content to possess their traditional mountain homeland but lately they have been bent on conquest and domination.  It is rumored that an ambitious human warlord named Decius has somehow come to lead them on this aggressive path.  They first conquered the fertile river valley and coastland to their south and have now turned their attention to the resource-rich wilderness to the west, so it appears that the lands to the north and east are safe for now.       

   However, for some reason that isn't exactly clear to the people in your village, the Jotnar have also been abducting young women from these neighboring lands at an alarming rate.  There are rumors that they use them for sexual purposes but... how could that even work?
